Man, this reminds me of when I spent a whole weekend picking a new coffee grinder and ended up just using the old one out of spite. For a 300 episode show I'd say just pick subs and move on, cause the dub cast can change halfway through and that throws me off way more than reading does. I got burned on one long series where they swapped out a main voice in season 4 and I didn't even notice for ten episodes. Reading fast is a skill anyway, you get used to it after like 20 episodes. Six weeks of spreadsheets is longer than most shows take to hook you, so just start watching.

So you spent a whole weekend doing science experiments just so your sister could steal the recipe for her party? Does she at least have to admit the orange juice thing was wrong before you hand it over?

Did you notice how this same trick shows up in other places once you start looking? Like how a photo can look totally normal until you zoom in and see the shadow going the wrong way, or how a "live" TV interview can have a tiny lip sync slip that gives away it was pre-recorded. I got burned last year by a clip of a city council meeting that turned out to be cut together from two different days, and the only tell was how the room noise changed for half a second when he took a breath. It's wild that our ears can catch stuff our eyes just breeze right past. Once you train yourself to hear those little jumps, you kind of can't unhear them, and it makes you slow down before hitting share on anything.
